Post cleanse, eating way too much

I am on my 5th day off of the cleanse and I am having a problem saying no to my cravings. Last night I went to California Pizza Kitchen and I had the Carne Asada Pizza. I even ate more then I usually do. Before the cleanse I was very diligent about portion size and eating healthy and now it's like I just can't get enough food. I used to measure out my cereal in the morning to ensure that I was only eating one serving, this morning I probably had 3 servings. Is this some sort of phase I am going through? I feel like "I made it through that entire cleanse and one of the first things I eat is a Carne Asada Pizza, I mean, come on!"
